As shown in Figure 1 to Figure 3, the insulator 11 of execution mode 1 has: the roughly main part 11a of U font, it winds the line 17(with reference to Fig. 5 to 7 for reeling); And the roughly 11b of pair of flanges portion, the 11c of U font, they are arranged on the two ends of main part 11a, are formed with the volume groove 11d using main part 11a as bottom between the 11b of pair of flanges portion, 11c.
Be formed with through hole 11f at the flange part 11c of insulator 11 and the wall body inside of main part 11a, this through hole 11f has at the flange part opening 11h of the peripheral part opening of flange part 11c with at the main part opening 11g of the peripheral part opening of main part 11a, and this through hole 11f connects the wall body inside of flange part 11c and main part 11a.In through hole 11f, bury conductive component 13 underground, protrude from flange part opening 11h one end of this conductive component 13, and the other end extends near main part opening 11g.
As shown in Figure 4, be provided with junction chamber 11k near of the main part opening 11g of through hole 11f, this junction chamber 11k is for conducting electricity the initiating terminal of the coiling 17 of inserting from main part opening 11g to be connected with conductive component 13.The height of junction chamber 11k is 2 to 3 times of height of main part opening 11g.
The initiating terminal of coiling 17 and the wall portion butt of junction chamber 11k that insert from main part opening 11g, bend to hook-type and engage with conductive component 13, plays the effect of chock and prevent from coming off.Conductive component 13 is by inserting from main part opening 11g coiling 17 initiating terminal, injects scolder or conductive paste etc. in from flange part opening 11h to through hole 11f and has the conductor of mobility and be solidified to form.In addition, the protuberance 13a of conductive component 13 can, by injecting after scolder or conductive paste in through hole 11f, be inserted into flange part opening 11h by electric wire, and scolder or conductive paste are solidified to form.
